Description
The MUonE experiment at CERN is motivated by longstanding questions surrounding the muon's anomalous magnetic moment, which would be sensitive to contributions from new physics. However, the precision of its Standard Model theory value is limited primarily by the leading-order hadronic vacuum polarization term. MUonE will determine this term using a new approach, by measuring the shape of the differential cross section for elastic scattering of 160 GeV muons on atomic electrons in a low-Z target; this process is sensitive to the hadronic running of the electromagnetic coupling α. A pilot run in summer 2025 is expected to provide the test data needed to establish control of systematic effects. We will present the status of the experiment, first preliminary results, and future plans.
